1994 Ford Explorer 6 cyl Four Wheel Drive Manual?Broke miles
Hey guys, I have a 2004 ford explorer 4.0 v6 engine and dash in an 88 ranger with ranger drive train. Put together to be used as a mud truck for the past few years and has been beaten up on but dosent want to die. It drives pretty good for an old beat up truck
**My concern is that the engine has**
(1)very slight (idle mainly) misfire symptom,
(2)hesitates when accelerating from its set 600 rpm idle but pretty much smooths out after 2000- but no real hesitation accellarating from about 1000 rpm on up, (3)i THINK that most of the problem occurs once the check engine lite comes on(usually about a minute after starting).
(4)intake manifold is loaded inside with black greasy carbon stuff
**things I did to try and fix it so far**
(1) I changed the plugs, wires, and coil(checked and double checked wiring configuration so thats not it)(2) sprayed fuel injector/throttle body cleaner in throat(while off and while running-and wasnt really able to remove intake hose thing too far off throttle body throat without it stalling
(3)removed air filter-ran the engine-and reinstalled it(no change)
(4)removed MAF sensor plug while it was running and didnt hear a difference even when I revved up th motor(i think its called that-sensor right there with air filter?)
`really strange that it would stall when I pulled the rubber intake off the throttle body but not when I disonnected that sensor
Please help!- I dont want to dump more useless money into this old mud truck
have the same problem?
